gray slightly suffused with ochreous in the submedian fold and heavily shaded 

 with blackish in costo-median and subterminal areas; t. a. line geminate, black, 

 partially white-filled, irregularly dentate with outward angle on cubital vein 

 and inward tooth in the fold ; orbicular obscure, round, largely lost in the dark 

 costal shading; renifomi conspicuous, whitish, with central lunate dark streak; 

 t. p. line obscure, oblique at costa followed by whitish shading, bent around 

 reniform and almost touching it with inward curve in the fold and outward 

 tooth on vein 1 ; s. t. line defined by dark shading in s. t. area, inwardly oblique 

 from apex to vein 6, bulging outwardly across veins 3-5, curved inward in the 

 fold and bent outward above inner margin ; apical area white-shaded ; a ter- 

 minal dark line ; fringes smoky, deeper basally. Secondaries smoky-ochreous 

 with heavy, broad, smoky outward border partially broken by ochreous shades 

 in extreme terminal area; traces of a curved t. p. line preceding this border; 

 a heavy dark terminal line ; fringes pale at base followed by a smoky area, 

 the tips being whitish. Beneath primaries smoky, sprinkled lightly with whitish 

 and with a round pale discal spot ; secondaries paler than above. Expanse 

 28 mm. 



Habitat: Prescott, Arizona (June, Sept.) 2 9. Types, Coll. Barnes. 



The lack of definite structural characters would seem to place 

 the species in Stilbia; in maculation it seems fairly close to the type 

 of the genus, anomala Haw. 



ACOPA BISTRIGATA Sp. HOV. (PI. XVII, Fig. 18). 



$ antennae thick, serrate and fasciculate ; proboscis wanting ; front rather 

 roughly prominent ; thoracic vestiture rough, scaly, mixed brown and white ; 

 abdomen grayish, untufted ; legs heavily clothed with thick brown hairs; pri- 

 maries short, broad, light brown, shaded with paler, basal area darker ; t. a. 

 line broad, white, straight to submedian fold, then with a prominent outward 

 tooth above vein 1 ; a broad white discal dash continued by a white line to inner 

 margin, subparallel to t. a. line; a white line at apex of wing preceded by a 

 large dark brown patch ; a ruddy brown broken terminal line ; secondaries 

 pinkish-brown. Beneath primaries smoky, tinged with ruddy with a white 

 dash at apex and another a short distance from it on costa, the area between 

 being brownish ; secondaries pale, sprinkled with ruddy-brown with a brown 

 apical patch and traces of a curved postmedian line. Expanse 21 mm. 



Habitat: Paradise, Cochise Co., Ariz. (Aug.); Huachuca Mts., Ariz. 

 (Aug.) 2 $ . Types, Coll. Barnes. 



The reference to Acopa is not very satisfactory although it runs 

 out to this genus by Hampson's key; the heavy hairy clothing of the 

 legs and the general appearance point to a new genus, but we are loath 

 at the present time to create a new one, and place it provisionally here.
